    Hey Timmur, Been Looking For You A While Now.

    How did your O2Grow oxygenator work out for you now you have some experience and DO testing behind you? Did the O2 generator maintain DO Supersaturation continuously throughout months of the growing cycle as advertised? In your opinion is the cost worth the stealth, increase in DO Sat., better...

    Mg Rox – Boundaries Of “safe Do Saturation Range” Related To Hydroponic Cannabis Cultivation For Fun

    Hello Mr. MG, It’s been a while since we communicated last April. Just wondering if you have read or heard of any new (within the last year) scientific research published worldwide addressing intensive hydroponic cannabis oxygenation, specifically targeting the minimal safe lower DO Sat. and the...

    Rdwc Low Dissolved Oxygen Saturation Causes Root Rot Outbreaks

    If you have never had root rot outbreak in a RDWC this thread is totally meaningless and not worth the little time it takes to read it. But, if you do RDWC and you have had a Pythium outbreak, made tea concoctions and tried to cure it or loaded your nutrient water with H2O2 and Clorox and killed...

    Let’s Confuse Oxygen With Air Some More… What Is The Difference In Rdwc

    Writers and salesmen love to create confusion between air and oxygen, it so easy to play with words. Air, oxygen and nitrogen all smell, taste and look the same so who will ever really know the difference without testing the dissolved oxygen saturation/concentration in nutrient solution – of...

    Rdwc – What Is Optimum Do Sat Necessary For Plants And Microorganisms The Entire Growing Season?

    They say having "plenty of oxygen" is vitally necessary for successful RDWC Hydroponics. Does "plenty of oxygen" mean "plenty air" or "plenty aeration?" Need some of your expert opinions with this one. Having no luck finding anyone that has any idea what DO Saturation is really requires and...

    Dwc And Oxygen (an Essential Nutrient), Not Air, Aeration Or Hydrogen Peroxide (h2o2)

    Lately, I’ve been reading about the positive effects of dissolving oxygen continuously to insure minimal safe DWC dissolved oxygen saturations and even DO supersaturation. Water that is low in DO is evidently a problem for some farmers, root zone hypoxia, fungi proliferation, root damage, all...
